Frequently asked questions

How fresh are the strikes shown around Philadelphia?

The lightning layer is a snapshot of the last 10 minutes — it is fetched when you switch the layer on, and reloaded when you move the map view substantially, so older strikes drop out on their own. The storm cells underneath refresh hourly; the timestamp under the map tells you which hour is on screen.

How far away is the lightning?

Sound covers about one mile in five seconds, so counting the seconds between the flash and the thunder and dividing by five gives you the distance in miles. The map shows it directly — each bolt sits where the strike was located.

Will this page warn me before a storm reaches Philadelphia?

No. It shows what is happening at the moment you open it. The app is what pushes a notification ahead of the cell, even while closed. Official watches and warnings come from the National Weather Service at weather.gov.
